After the unit has acquired GPS, it will lower the reflector to the
proper elevation for a satellite search in your location. As the unit
scans the proper elevation, it will locate satellite signals. The antenna
will return to a scanned satellite location and verify the satellite’s
DVB identification. If it is the correct satellite, the antenna will peak
on the signal and stop. If it is not the correct satellite, the unit will
move directly to the correct satellite, stop and peak on the satellite.
The unit will continue the conical scan for approximately 6 minutes.
After 6 minutes, the unit will enter “sleep mode” and end the conical
scan.
4.3 Tracking with the RoadTrip LP
To track with the RoadTrip, simply power on the unit using the
power switch. The antenna will go through the same acquisition
routines as it did while searching in the stationary mode.
If the unit was already locked on a satellite, you only need to begin
moving. After the antenna unit senses forward movement at 10 MPH,
it will actively track the satellite or begin a satellite tracking search
routine to find the desired satellite signal.
The antenna uses active gyros to determine vehicle movement
and adjusts the antenna accordingly. Once the desired satellite is
located and identified, the RoadTrip will stay actively locked on the
satellite by using a conical tracking routine. If the vehicle stops while
tracking, it will continue to actively track the satellite for up to 6
minutes. If the vehicle is stationary for more than 6 minutes, the
unit will go into “sleep mode”, stop actively tracking the satellite and
end the conical search.
4.4 Satellite Signal Interruption
Satellite TV reception systems may be disrupted by weather condi-
tions. Satellite signals may be lost temporarily during a steady
rainfall. Rain, snow or dew on the surface of the radome can ad-
versely affect your satellite signal. It is important to maintain your
radome with the approved protectant, and remove water or snow by
wiping it off when necessary.
While moving, the signal can be interrupted when line-of-sight to the
satellite is blocked. Tunnels, highway overpasses and dense urban
areas are a few of the obstructions that may cause signal loss
while in motion. If the signal is blocked for more than 15 seconds,
the antenna will automatically return to a search routine.
The antenna will only
track the satellite while moving
forward. If you back your
vehicle, you may lose satellite
acquisition. Turning quickly
when first moving may cause
loss of signal.
If searching for the 101
DIRECTV satellite, the antenna
will verify the 110 satellite prior
to stopping on 101.
The antenna has an auto-
matic peaking routine to maintain
the best signal while in sleep mode
or in a stationary position.
GPS acquisition will nor-
mally take less than a minute. If you
have traveled a long distance with-
out using the antenna or if the dish
is being used for the first time, ac-
quisition may take several minutes.
See Appendix C for peri-
odic maintainance requirements.
